INVENTOR \V [TN ESSES ATTORNEY v fully clear the coupler and draft sills and to be always below the double crank 1 53, hereinafter more full described in all positions of the same.

The actuating arm 10 is connected with the arm ll of the operating lever (3 in such a Way that there Will be a positive and directlv acting force controlling the move ment of the lever (l. and a particulail feature of this invention is the connecting, of those members so as to permit free movement of the coupler Without moving the pull arm 10 in a manner or to an extent to allect the internal coupling" mechcanism Within the coupler head. For this purpose a double crank 13 has its'crotch 15 pivotally mounted in a bracket 16 fixed to the upper side of the lower flange of the draft sill adjacent the arm 14-.

Forming the pivot arms of the double crank 13 are the longitudinally extending alined shafts 1? and 18. the shaft 1? being; pivotally mounted in the looped end 11.9 of the arm 10, which engages the same below the bracket 16. Theshatt 18 parallels the coupler in its normal. position and extends forwardly ol the end sill C a distance at least as great as the maximum longitudinal travel of the cruipleri l'llidahlv iji'iountedupon the shait 18 is the looped end 20 of a Z-shaped linkll. the opposite and forward end of which is 'l'lUFlllQ l into a hook which engages in an eve 2?} in the arm of the operating lei (1, lift means of this connection it will he seen that the rou iiler is 't ree'to more either l mgritudinall i; or to swing transversely of it selll the link merel slide ing or rotating; on tl" ehaitt l8 and vet irrespective oi. operator can drau the handle 11 outwardly until the parts take the pt i n shown in dot and, dash lines. of Fi which action will quickly and positivithe crank 13, thcrehvpushing: on tuate thelevcr ti 6 and supporting device as shown several tip ures.
